I am using mod_wsgi for python 2.7 and it completely works well
without zmq things.
And zmq works well when it used stand alone.
I don't know why mod_wsgi cannot import zmq.
Plus, it does not work even if I remove add site-package things.

i am trying to make web site which retrieves query from the user, and

used python script which gets the query and send the query to C++

I got an error message like this;

The code below shows how I implemented it. Please help me
import site
site.addsitedir(D:\\util\\Python27\\Lib\\site-packages)
Why are you needing to explicitly add site-packages into sys.path?
This immediately suggests you are doing something wrong as it should
not be necessary.
Is mod_wsgi.so you are using for Python 2.7? Did you install Python
for all users or just the user you installed it as? You are supposed
to install it for all users.
Presuming that zmq module has a C extension component, is that module
compiled as 32 bit for the Python version mod_wsgi is compiled for?
